Since both barrels are made in the same factory at the same time, it is hard to say.
But since Sako has the the higher standard, it could be by their firearms command the higher price...but as far as I am concerned, as good as the Tikka's are, they just aren't as nice as the Sako's. Or offer the same features. And in handling them side by side, you can immediately see and feel the difference. So, yes...they are the real deal!
And for the features that they provide, you cannot build a custom rifle with the same quality options for the same price.
Now ain't that the truth .. strange how some wanna spend big bucks on a custom ( and reloading ) when the rifle they really should have is at Cabela's
funny but true
